Application fi1ed Ju1y 21,-'1915, Serial No. 41,029. Renewed August 27,

To all whom it may concern:

Be it known that I, JOHN YSEKINGER, a citizen of the United States,residing at Ford City, in the county of Armstrong and State ofPennsylvania, have invented certain new and useful Improvements inMagnetic Separators, of which the following is a specification.

The invention relates to magnetic separators, the particular embodimentillustrated herein being designed for use in removing magneticparticles, such as iron, steel, iron rust, and the like from the batchemployed in the manufacture of glass. The primary objects of theinvention are the provision of a cheap, simple construction which willeffectively separate from the batch the magnetic materials containedtherein; the provision of a separator which will accomplish the functionabove stated without causing any unmixing of the batch; and theprovision of a cheap, simple construction and compact form. Certainembodiments of the invention are illustrated in the accompanyingdrawings wherein- Figure l is a vertical section through the apparatusembodying my invention, Fig. 2 is a plan view of that part of theapparatus of Fig. 1 below the discharge hopper, Fig. 3 is a section onthe line III-III of Fig. 1, Fig. 1 is a diagrammatic side elevation Viewof a modification, and Fig. 5 is a diagrammatic side elevation of stillanother modification.

Referring to Figs. 1, 2 and 3; 1 is the batch hopper containing thematerial from which it is desired to remove magnetic particles; 2 is avalve for controlling the hopper; 3 and 1 are pole pieces having shanks5 and 6 carrying the windings 7 and 8; 9 is a collar carrying the shanks5 and 6 and constituting the means to which suspending means forsupportingthe separator may be attached; and 10 is a bucket or conveyerinto which the material passing the separator is discharged.

The pole pieces 3 and 4 have their end faces 11 and 12 inclined asindicated in Fig. 1, the lower portions of such faces approaching eachother to form a narrow slot 13. The outlet 14 of the hopper comprises anelongated slot of relatively small diameter spaced a considerabledistance above the Specification of Letters Patent.

pole pieces. The valve 2 is of tapered elongatedform as will be seen byreference to Fig. 3 in connection with Fig. 1 and is provided with ashank 15 by means of which the valve is raised and lowered. The shanksof the pole pieces are securely attached to the horizontal collar 9preferably of cast iron, and it is by means of this collar that theseparator is suspended by the eyes 9 and cables 9 at any desiredelevation with respect to the hopper 1.

In operation, after the receiving bucket 10 has been placed in position,the valve :3 is raised and the material allowed to tie" through thespout 141. The resistance of air to the downward flow of material cause;

strike the inclined faces 11 and 12 thus .Ql ing the magnetic forces anopportunity t1; act upon any magnetic particles contained in the batch.These magnetic particles are worked downwardly along the faces 11 and 12by the stream of batch and finally reach a position upon the lowerhorizontal faces 16' and 17 of the pole pieces. When the bucket 10 isfilled the valve 2 is closed and the bucket removed. The magneticparticles adhering to the surfaces 16 and 17 are then easily removed bybreaking the current through the windings 7 and 8.

Fig. 4: illustrates a modified form of apparatus wherein the hopper 18discharges between the pole pieces 19 and 20 having the inclination oftheir front faces 21 and 22 the reverse of that shown in Fig. 1. Theoperation is substantially the same as that heretofore described exceptthat a portion of the magnetic material collected upon the faces 21 and22 remains upon such faces instead of all being carried to thehorizontal faces 23 and 24 as is the case in the construction of Fig. 1.

Fig. 5 illustrates another modification in which the opposing faces ofthe pole pieces are inclined as indicated at 26 and 27, the materialfrom the hopper 28 falling upon the inclined faces 26 corresponding tothe faces 11 and 12 in the. construction of Fig. 1. The magneticarticles collect upon the inclined faces 2 and horizontal faces 28.Aside from the pole pieces, the constructions in Figs. 1 and 5 followthat of Fig. 1.

What I claim is:

1. In combination, a pair of alined sub stantially horizontal pole,pieces spaced, apart and having inclined opposmg end faces forming atapering passageway and substantially horizontal botton iaces 1neet-. ghe ncl ned: a e an tetanus. a u e angles therewith, windings forenergizing the pole pieces, and means for supplying material into saidpassageway and upon the inclined pposing faces,

2. In combination, a pair of alined substantially horizontal pole piecesspaced apart and having inclined oppqsing end Copies of this patent maybe obtained for s-2s ri m iasa taper- 1 p ag y, and

having substantially horizontal bottom faces supported free to receivemagnetic particles andwvithsuclnfaces accessible from beneath, windingsfen; energizing the pole pieces, and a passage for supplyingmaterialtosaidpassageway, said passage having itslower end terminating at asubstantial distancenabeve the upper edges of the inclined faces topermit the material tospread before it reaches suchfaces.
